Q. In order to find the depth of the sea, a ship sends out a sound wave and receives an echo after one second. If the velocity of sound in water is 1500 m/s, what is the depth of the sea?

Answer 1

$$\begin{gathered} DearStudent, \\ totaltime=1sec \\ Timeforsoundtotravelfromdepthtoreciever=\frac{1}{2}=0.5sec \\ velocity=1500m/s \\ dis\tan ce=velocity\times time \\ dis\tan ce=1500\times 0.5=750m \\ Regards \end{gathered}$$
